The year 2017 may become a historic milestone where the visceral effects of global heating – extreme storms and wildfires – finally reach public consciousness.

 Homeowners Access Hurricane Irma Damage – 12 Sep, 2017

Humans have known about the effects of carbon in the atmosphere for two centuries, since the work of Joseph Fourier at the French Academy of Science. A century ago, Swedish chemist, Svante Arrhenius, calculated that doubling atmospheric CO2 would increase Earth’s average temperature by 5-6°C, which now appears accurate. In 1981, Dr. James Hansen wrote the first NASA global temperature analysis, and in 1991, the UN convened the first climate conference in Berlin. As of today, none of this has significantly altered the actions of human society enough to actually reduce carbon emissions.

In the last few years, we have witnessed more wildfires and violent storms that are directly linked to global heating. This year, communities around the world have experienced a dramatic increase in climate-related natural disasters, costing thousands of lives and billions of dollars, and leaving behind devastation. 

Year of the fire

I’ve lived on the west coast of Canada for 45 years, and during that time, I’ve witnessed a few days of smoke from wildfires in the interior fir and cedar forests. For the past two summers, however, the entire coast has been blanketed in thick smoke through July and August, the summer sun barely piercing the haze. Citizens experience respiratory problems, tourism is disrupted, and firefighting teams from the northern and southern hemispheres now routinely trade support teams in alternate seasons.

In February, the North Pole experienced a staggering +30°C temperature anomaly, unprecedented in modern record-keeping. The melting permafrost releases methane gas, a greenhouse-gas far more powerful than CO2. The Arctic contains about 1.8 trillion tons of carbon, stored as methane, and the UN Intergovernmental Panel on Climate Change has not yet accounted for this significant positive feedback of global heating. The 2017 data so far shows that over the last decade, Earth is heating about twice as fast as IPCC scientists had predicted.

Grass Fire in the Astrakhan Nature Reserve, Russia – 13 Mar, 2015

This extra heat means drier grasslands and forests, resulting in more frequent, more intense fires. Warmer temperatures add moisture to the atmosphere, which we might assume would dampen fires, but it has the opposite effect. Increased precipitation during the winter means that grasslands grow more. Then, during the drier summers, this extra growth becomes added fuel to the fires. Even a fraction of a degree increase to winter temperatures allows insects like pine beetles to move toward the poles, into boreal forests, killing more trees that also add fuel to fires.

During the summer of 2017, fires raged across Europe, killing hundreds, devastating communities, and leading the European Union to declare a state of emergency. Portugal suffered the worst fire season ever recorded, scorching almost 520,000 hectares of forest. It was six times the annual average for recent years, and killed over 100 people. The Interior Minister, Constanca Urbano de Sousa, remarked that she had wanted to quit after 64 people were killed in June wildfires and after investigators had chastised the official response. When October fires killed 42 more citizens, de Sousa resigned.

Meanwhile, four people died from fires in the Galicia region of northwest Spain. Fires in Croatia destroyed homes and other buildings in the village of Podstrana, and the historic town of Split. Along the Dalmatian coastline of the Adriatic Sea, grasslands and woods burned, along with homes, cars, and public buildings. On the southern Adriatic coast, in Montenegro, fires burned through the historic Lustica Peninsula town of Tivat, which had to be evacuated. Montenegro, unprepared for the scale of fires, asked NATO for firefighters, aircraft, and assistance with evacuations.

In Italy this year, some 900 wildfires burned over 130,000 hectares. Residents and tourists were forced to evacuate parts of Rome and Naples, including Mount Vesuvius national park and the Castelfusano coastal pine forest, south of Rome. A beach resort on the island of Sicily had to be evacuated. This is a typical impact of global heating. Italy experienced 30% less rain and 30% more wildfires. In July, fires burned near Castagniers and Nice, in southeast France and on the French island of Corsica. In southwest Turkey, fires destroyed 40 homes as communities evacuated. 

July was the hottest month in 130 years of Moscow’s recorded climate history, and smoke from fires blanketed the region. Within a few days in July, fires burned some 150,000 hectares during an historic heat wave and drought.

In May, under record high temperatures and dry conditions, China and Mongolia grew even hotter and drier, leading to some of the largest fires on Earth in recent history. Fires burned through the Greater Hinggan Mountains, threatening the Hanma Nature Reserve and the city of Hulun Buir. In early July, Mongolia’s National Emergency Management Agency fought 11 major forest fires across northern Mongolia, exhausting their supply of fire extinguishing equipment. President Khaltmaa Battulga and Prime Minister Jargaltulga Erdenebat prohibited people from entering the forest areas, called an emergency meeting, and instructed their engineers to attempt creating artificial rainfall. Legions of Mongolian citizens, communicating through social media, joined the fire brigades, but by the end of July, they faced more than 20 major fires, some threatening the capital at Ulan Bator.

Fires in western North America, broke records in Alaska, Canada, Washington, Oregon, and California. The Seattle region experienced a +10°C temperature anomaly in August as fires burned through Washington state forests. Wildfires ravaged Oregon and killed 30 people in northern California, destroying some 3,500 homes and businesses in California’s wine region, obliterating neighborhoods. Throughout the western United States, over a million hectares burned this summer.

Santa Rosa, California, fire devastation – 13 Oct, 2017

“Climate change is turning up the dial on everything,” said LeRoy Westerling at the University of California. “Dry periods become more extreme, wet periods become more extreme, and fires are increasing. The ecosystem is changing.”

Extreme Storms 

Global heating has increased ocean temperatures, adding energy to storms. By October, the year 2017 already approached the all-time record for both total measured storm energy and accumulated damage. This summer, hurricanes Nate, Harvey, Irma, and Maria pounded the Caribbean and Southeastern US. According to the National Oceanic and Atmospheric Administration, the US has experienced 15 weather disasters this year that cost more than $1 billion, an all-time record. A study from 13 US federal agencies concluded that “extreme weather events have cost the United States $1.1 trillion since 1980.” 

Hurricane Harvey Flooding Rescue in Texas – 27 Aug, 2017

Storms have been getting stronger since the mid-1980s. An analysis of 167 years of data by the Associated Press found that no 30-year period in history had seen this many major storms. Typically, North Atlantic ocean temperatures remain too cool to support hurricane-level storms. This year, warmer than normal North Atlantic temperatures fueled tropical storm Ophelia to hurricane status on October 14, as it moved toward Ireland. Hurricane-force gusts of 192 km/hour hit Ireland, flooding coastal towns, and causing structural damage, vast power outages, and two deaths.

The Atlantic coasts of Ireland, England, France, Spain, and Portugal now face, for the first time, the sustained threat of hurricanes. Four years ago, the Royal Netherlands Meteorological Institute predicted that by 2100, global warming would increase the frequency of hurricane winds in western Europe.

The extreme fires and storms of 2017 signify more than just a ‘new normal’. With each fraction of a degree that Earth’s average temperature increases, these fires and storms will increase in intensity. The effects of climate change are not linear. A one-degree increase in temperature will yield about four-times the intensity of fires and storms. Some evidence suggests that by mid-century, fires and storms could double in their destructive power. 

A study published in Nature suggests that limiting global heating to the Paris goal of 2°C is now “unlikely”. The UN now estimates that the median projected global temperature increase is 3.2°C with a likely range up to 4.9°C and a high end of 8°C. The “new normal” will be constant change; a growing intensity of storms, fires, and other extreme weather, for as long as human carbon emissions continue.

Even if it sounds hopeless, it’s not. We have the chance to act decisively to change our present. All we need to fix this massive challenge is at our disposal.  We just need the courage to come together and make it happen.
